I do apologize if this is already in a comment stream, but I'm not finding it...We've been asked by the reviewers to update our FTEs and the new Pif3 form requires the "daily average calculated on a yearly basis" for both FTE and transients; this is added to make "total building users as a daily average" after which there is a "Note: Equals the sum of FTE and transients expressed as an annualized daily average". Annualized daily average means that you divide the number by 365. So if you have an average of 1,000 visitors for the 300 days that your building is in operation your daily average is 822 visitors. On the other hand "average per day on a daily basis" implies an "average day" ie 1,000 visitors" which is the figure we would be inclined to input. On the WEp1 and c3 credits you input the number of days of operation so the annualization is performed automatically, so I don't see why this would be necessary to perform in the Pif3 form. Just want to ensure that I'm doing this correctly--I'm not sure how to double-check our understanding; there is no reference to this in the LEED 2009 manual or, it seems, any post on LEEDUser etc. We are clear on all the other inputs. Thanks for your comments!

I have groused about vague definitions in the LEED FTE and occupancy documentation elsewhere on this page, and this is another case. i would guess that if you have 1000 visitors each of 300 days, then you should still use 1000 as "Total Building Users as a Daily Average", to properly calculate toilet flushes and handwashes later on. I would create a very detailed note to upload along with PIf3, explaining your exact methodology, and define the terms you are using. Also, when you get to WEp1, double check the numbers that come over from PIf3, and change them (with a detailed explanation) if they are screwed up. I keep finding WEp1 double-counts transient occupants.

I think you are right to propose doing it that way. Will be interesting to see if anyone else is certain about this. We actually have a fairly complicated situation because a small dormitory exists that operates for 365 days, so we need to separate that use. But I agree that we should be able to see how the inputs affect the linked submittals. We'll be updating everythin to VO4 format and look at the effects carefully. I'll post anything I see that seems to clarify the issue.
